| Abstract: |
Prompted by the discovery from CO observations that the bulk of the molecular gas in close mergers can quickly congregate between the nuclei, we have begun to look at number of such systems, imaging the 1-0 S(1) and Brγ lines. In this contribution we focus on Mkn 266, an interacting galaxy system with 2 nuclei, one classified as a LINER and the other as a Seyfert. We discuss the excitation mechanism of the H2, with particular reference to the emission occuring between the continuum nuclei. It is likely to be shock excited as a result of the collision itself rather than from stellar processes or an AGN, and the evidence from a number of other observations is that this may be a common source of 1-0 S(1) emission in mergers. |
